and'State of Newl Jersey, have' invented cer- Cages *for Closed' Journal-Boxes', fully describedfandfrepresented in the following spefi'cation and thel accompanying drawings, forming avpartfof the' same.

'This'"inventi'on` relates to that class of 'rlleit'bearingsin which the casing is providedmwith. heads or. flanges. at the o posit ends hich l"cover the ends fof the' rol s, and necessitate the insertion of thel rolls separately through the central a erture or shaftopening in which the /sha t revolves when the bearing is in operation.

The objectof the invention is to furnish a so-called roll-guide .which may be conven- 'iefnt-l inserted through the shaft-o enino',

Y c P s and the rolls subsequently inserted into contact with the guide which operates to hold them in parallelism around the shaft. Such roll-guides are very common, but none have heretofore been made of suchl character that vit could be readily inserted through the shaft-opening 1 and operate effectively in connection with a series of loose rolls.

The invention consists of a skeleton frame having tie-bars upon its longitudinal edges 6 shows a one-bar guide.

and segmental heads g at its opposite ends suitably curved to fit within the periphery of the casing, while the tie-bars are disposed at' a suitable distance apartV to `embrace a given number of the rolls.

AThe invention will be understood by reference to the annexed drawing, in which-d Figure l is 'a cross section of the casing with one of the roll-guides inserted, another partly inserted, ard dotted lines showing the position for the last guide when fully inserted. Fig. 2 is a section on line .f-2 1n *Fiz 1; Fig. 3 is a 4section similar to Fig. 1

with the two guides and the rens funy inserted; Fig. 4 is an end view of the casing with a hinged guide represented in the central aperture; and Fig. 5 is an end view of the casing and rolls shown in Fig. 3. Fig.

the aperture and extended partly inside the casing. The roll-guide is thus a mere rectangular skeleton frame adapted to embrace loose rolls with the bars @fitted radially between the` rolls, and set at such ya distanceV apart as to just embrace a given number, as two or three, of the rolls. As the segmental heads g occupy a certain space between the flanges c, the rolls which lie between the tiebars e are made shorter than the rolls which are not embraced by the guide, and rolls of two different lengths are therefore required to form the series within the casing.

To' prepare such a roller bearing for the application of the shaft, one of the rollguides is first inserted through the aperture l and dropped to the bottom of the casing, as shown in Fig. l. Two of the rolls of suitable length to fit between the segments g are then dropped within. the guide, and an additional roll inserted between them, pushing them laterally against the tie-bars e, as shown at the bottom of Fig. 1. Two rolls of suitable length to fit between the flanges c may then be placed within each side of the casing, and a second roll-guide inserted and-pushed upwardly to the position indicated bydotted lines in Fig. l.` An additional roll may then be crowded between the rolls at opposite sides of the casing, forcing one of each pair against the upper rollguide, as shown in Fig. 3. Two rolls may then be inserted in the upper guide and an additional roll forced between them, thus supplying t-he entire twelve rolls to the bearing in connection with the two guides having four guide-bars. To hold the rolls 1n place while such a bearing may be in transportation, or just before its application to the end of a shaft, a wooden plug of the same size as the shaft may be inserted as and 2, wl'iere one ofthe guides is-shown in indicated by the circle 'h inl Fig." 5, and serve to hold the* rolls 'in'place While the shaft is inserted, and until the shaftv pushes .the plug entirely from' the casing. x Vith "the proportions shown in Fig. 3, each of the `roll-guides embraces one-quarter -of the casing and carries Within'l it onequarter of the rolls, but the guides may be made to carry one-fifth of the. rolls .or onebe required to make t eguides small enough to enter the casing throughout the aperture al. Having thus set forth the natureofthe invent-ion What is claimed herein is: v

1.I The combination, with a roller bearing casing having fianges upon the ends adapted to Wholly cover the rolls, vat least oneof such flanges having a lcentral aperture for the passage of the shaft, of a rectangular skeleton roll-guide proportioned Ito ass through the shaft-aperture into the casing, andloose rolls adapted to fit loosely within such rectangular yroll-guides. v v

2. The combination with ja roller bearing y casing having integral flanges upon its ends sixth, or any other:proportionl which may adapted to wholly cover the ends of 'the rolls,` and having central apertures for the iiissage of the shaft, of aseriesof roll-guides having segmental heads at the ends and tie-bars upon 'their longitudinal edges and Aproportioned to. pass through the shaft-aperture into the :ca si'ng, and loose rolls adapted to lit loosely in the space between the heads and side-bars of the guides. y '1 l 3. l'The combination, with a roller bearing v35 casinghaving a central shaft aperture and`1 yflanges around such .aperture to cover the rends'of the rolls, of a'. rectangularl skeleton v roll-guide proportionedto pass through vthe shaft-:aperture into the casmg, and having 40 at its ilongit'udinal edges radial `tie-bars and the outer edges of such tie+bars beveled oif .j4
